I just wanted to put in writting my appreciation for everything your company has done for me recently. The replacement for my 664 mixer arrived today and is working perfectly. Please pass on my thanks to Matt for his patience, expert help and the guidance he has provided despite me phoning, in a panic, from various locations around the world. Thanks to you all for going beyond the call of duty, the level of service has been absolutely fantastic!
Active or Passive Wide-Band LPDA Antenna
LPDA-A-WB
The LPDA-A-WB may be used in an Active or Passive Mode to suit individual applications:
Active Mode with fixed Bandwidth in the 470-960MHz range (custom tuned in Bands) with user adjustable gain of 18dB
Passive Mode (when there is no dc present) can be used as a High Gain, passive antenna to receive or to transmit within the in-built filtering filter range, passive gain boasting 5dB.
KEY FEATURES:
This unique design has an exceptionally low loss and a very selective Band-pass filter with fixed bandwidth. The LPDA-A-WB V2 offers flexibility as well as additional front-end protection against interfering dirty RF, the booster offers 18dB user adjustable gain to compensate long antenna extension cable losses hence increased distance between the transmitter and the receiver, LPDA-A-WB finds its application in film making, documentaries, fixed installations as in studios, and theatres. Compatible with any UHF wireless receiving systems (Digital or Analogue) providing a directional coverage pattern.
The antennae are constructed using advanced multi-layer PCB design technique with copper-clad epoxy fiberglass to withstand heavy duty use in harsh environments, providing long life and consistent performance under difficult operating conditions. The booster box is a custom-design machined aluminum, black anodized with water resistant O-ring mounting. Mounting is made easy with integrated thread that directly mounts on to a tripod or with the supplied adaptor it can be mounted directly on to a microphone stand. Powering is through coaxial cable, power source of 10-18Vdc.
